Models were annotated by projecting transcripts annotated by Ensembl from a reference genome, through a BLASTZ DNA alignment of this genome to a reference genome

Frameshift introns

<p><strong>Frameshift introns</strong> are the length of 1, 2, 4, or 5 basepairs. They are introduced by the Ensembl <a href="../../../info/genome/genebuild/index.html">genebuild</a> in order to fit the cDNA sequence to the genome.</p>Frameshift introns occur at intron number(s) 40, 49, 50, 51, 53, 54, 55, 56, 57, 58.
